Will precipitation occur when the following solutions are mixed? If so write a balanced chemical equation for the reaction. Na2NO3 and AgNO3NaNO3 and NiSO4FeSO4 and Pb (NO3) 2

Answer and explanation;

(a) Na2CO3 and AgNO3 - Precipitate formed.

Na2CO3 (aq) + 2 AgNO3 (aq) → 2 NaNO3 (aq) + Ag2CO3 (s)

Silver carbonate is the precipitate formed

(b) NaNO3 and NiSO4-No Precipitate formed

(c) FeSO4 and Pb (NO3) 2 - Precipitate formed.

FeSO4 (aq) + Pb (NO3) 2 (aq) → Fe (NO3) 2 (aq) + PbSO4 (s)

Lead sulfate (PbSO4) is the precipitate formed in the reaction

Precipitation reactions refers to the formation of an insoluble salt when two solutions containing soluble salts are combined.

The insoluble salt that is formed is known as the precipitate, hence the name of the reaction.
